Worn Out

I'm not sure if it's old age, sleep apnea, a spiritual attack, or just a phase I'm going through, or maybe a combination of it all, but I am worn out! Last night I went to bed at 9:30, was asleep by 10:15, got up once in the middle of the night, and again at 6:45 am, which is fairly normal for me, but was exhausted after all that sleep. I'm reminded that the scripture says that the job of the enemy is to wear out the saints, I don't want to over spiritualize anything, I'm not that spiritual, neither do I want to give the enemy much credit, but I'm tired and can't seem to get rested up. My friend and pastor says he's feeling the same and mentioned getting B-12 shots, but they give you those in the butt and from what I hear they really hurt...I'm not going that route! Perhaps I need to double my daily vitamin and see what that will do...maybe it's time to admit it...I'm getting old!
